    Gastrointestinal ( GI MESHD) symptoms of SARS-CoV2/COVID-19 in the form of anorexia HP anorexia MESHD, nausea, vomiting HP nausea, vomiting MESHD vomiting MESHD, abdominal pain HP abdominal pain MESHD and diarrhea HP diarrhea MESHD are usually preceeded by respiratory manifestations and are associated with a poor prognosis. Hematochezia HP Hematochezia MESHD is an uncommon clinical presentation of COVID-19 disease and we hypothesize that older patients with significant comorbidites ( obesity HP obesity MESHD and cardiovascular) and prolonged hospitalization are suspectible to ischemic injury MESHD to the bowel. We reviewed the clinical course, key laboratory data including acute phase reactants, drug/medication history in two elderly TRANS male TRANS patients admitted for COVID-19 respiratory failure HP respiratory failure MESHD. Both patients had a complicated clinical course and suffered from hematochezia HP hematochezia MESHD and acute blood SERO blood MESHD loss anemia HP requiring blood SERO transfusion around day 40 of their hospitalization. Colonoscopic impressions were correlated with the histopathological findings in the colonic biopies and changes compatible with ischemia MESHD to nonspecific acute inflammation MESHD, edema HP edema MESHD and increased eosinophils in the lamina propria were noted.Both patients were on anticoagulants, multiple antibiotics and antifungal agents due to respiratory infections MESHD at the time of lower GI bleeding MESHD. Hematochezia HP Hematochezia MESHD resolved spontaneously with supportive care. Both patients eventually recovered and were discharged. Elderly TRANS patients with significant comorbid conditions are uniquely at risk for ischemic injury MESHD to the bowel. Hypoxic conditions MESHD due to COVID-19 pneumonia HP pneumonia MESHD and respiratory failure HP respiratory failure MESHD, compounded by preexisting cardiovascular complications, and/or cytokine storm orchestrated by the viral infection leading to alteration in coagulation profile and/or drug/medication injury can be difficult to distinguish in these critically ill patients. Presentation of hematochezia HP hematochezia MESHD may further increase the mortality and morbidity of COVID-19 patients, and prompt consultation and management by gastroenterology is therefore warranted.

    In the setting of COVID-19 pandemic, only few data regarding lung pathology induced by SARS-CoV-2 is available, especially without medical intervention interacting with the natural evolution of the disease. We present here the first case of forensic autopsy of a COVID-19 fatality occurring in confinement and in a young female TRANS. Diagnosis was made at necropsy and lung histology revealed diffuse alveolar damage MESHD, edema HP edema MESHD and interstitial pneumonia MESHD pneumonia HP with a geographically heterogeneous pattern, affecting mostly central part of the lungs. This death related to COVID-19 pathology highlights the heterogeneity and severity of central lung lesions MESHD when the disease naturally evolves.

    With frequencies varying up to 20%, treatment resistant pulmonary failure MESHD is a major life-threatening complication in COVID-19 (SARS-CoV-2, HCoV19) disease pathology. Both acute respiratory distress syndrome MESHD respiratory distress HP syndrome ( ARDS MESHD), proposed to be caused by an over-reacting immune system which floods the lung with edema HP edema MESHD, a liquid consisting of inflammatory cells, and diminished lung perfusion, have been postulated to cause this treatment resistant lung failure MESHD. Aging, co-morbidities, male TRANS gender TRANS and obesity HP obesity MESHD are pre-existing factors associated with the more severe outcome. Thrombosis MESHD is more frequently observed than usually seen during ICU admission. Different hypotheses explaining the pathophysiological cascade leading to fast progressing severe COVID-19 disease and how to counteract it have been proposed. A variety of intervention studies to control severity are ongoing or planned. Not suggested so far, we here hypothesize that the inflammatory lipid modulator prostaglandin E2 (PGE2) executes a prominent role in COVID-19 pathophysiology. Based on this we suggest measuring PGE2 in patients and evaluating selective inhibition of the human microsomal prostaglandin E synthase-1 (mPGES-1) as a potential innovative therapeutic approach in this devastating condition for which sonlicromanol, a drug currently in phase 2b studies for mitochondrial disease MESHD, is a candidate.
